Importing data from legacy .dat files¶

This notebook shows you how you can import data from a legacy dataset generated with the old qcodes.data dataset. These are typically generated with qcodes.loops.Loop or qcodes.measure.Measure.

In [1]:

%matplotlib inline
from pathlib import Path

from qcodes.dataset import (
    import_dat_file,
    initialise_or_create_database_at,
    load_or_create_experiment,
    plot_by_id,
)

In [2]:

# in case it was not there already
initialise_or_create_database_at(
    Path.cwd().parent / "example_output" / "import_data.db"
)
# put the old data in a new experiment
exp = load_or_create_experiment("old_data_loading", sample_name="no_sample")

In [3]:

location2d = "./data_2018_01_17/data_002_2D_test_15_43_14"
location1d = "./data_2018_01_17/data_001_testsweep_15_42_57"

In [4]:

run_ids = import_dat_file(location1d, exp=exp)
axs, cbaxs = plot_by_id(run_ids[0])

Starting experimental run with id: 1.

In [5]:

run_ids = import_dat_file(location2d, exp=exp)
axs, cbaxs = plot_by_id(run_ids[0])

Starting experimental run with id: 2.
